Fig. 4.3 (Color online) Energy spectrum of the HCN − anion for J π = 0 + , 1 − , 2 + , 3 − , 4 + , and
5 − is shown as a function of J (J + 1). The dominant K J -component (4.32) is indicated. If several
components are present, the state is marked as “mix” (from Ref. [83])

Fig. 4.4 (Color online) Energies of the HCN − dipolar anion for J π = 0 + , 1 − , 2 + , 3 − , 4 + , and
5 − states in the complex-energy plane. These states can be classified into five groups labeled g 0 –
g 4 based on their complex energies. Bound states and near-threshold resonances belonging to a g 4
group and narrow resonances in a group g 3 are shown in the insert (from Ref. [83])
